The bottle mockup is placed perfectly. The shadows placed are not aligning, the bottle shadow makes it look it is lying on a surface and the orange shadows are making it look there's a table. You could add a label to the bottle mockup same as the bottle cap colour btw. I like the orange juice splash. The name Jack Juice Corner sounds weird, you could work on the name more. The little orange and leaf elements are perfect, makes it look breezy. Add more contact details down there like address, email and the number is there. the colour palette is fine, it's giving - healthy drink/natural/eye-catchy. I think it's goodwork yayyy.

The orange color you selected works really well—especially when paired with the gradient. It adds warmth and energy to the overall design.

looks simple yet interesting, looks like what the client wanted
